I’m not sure if the Quasar will take away my Expendable Anti Tank slot, so I might not be the best one to answer your question. But I can see some advantages over the autocannon.
It doesn’t take a backpack slot
It can one shot a lot of stuff
There’s no reload time, just a cool down time. So you can switch weapons and continue to fight/run
Unlimited ammo is pretty nice
Edit: I realize I didn’t quite answer your question since you asked about situations. I also haven’t used it enough to get a real good feel for where it shines.
The one thing the Quasar is really good at is shooting down dropships. One engine shot and it’s down. Does shooting down a dropship actually do anything? Not really, but it’s rad as hell.

Not only is it rad as hell, but you can smash the dudes that it just dropped off!
When I shoot before it manages to drop the bots it does quite a number on them. A couple of Quasars and bot ships drop like flies around the team.
When I see a flare go up, I get on MANPAD duty and eagerly await for the ship.
